DIE FOR CUTLERY.

SPECiFIGATION forming part of Letters Patent No. 479,668, dated July 26, 1892.

Application filed July 22, 1891. Serial No. 400,364. (No model.)

and use the same, when taken in connection with the accompanying drawings, in which Figure 1 is a face View of the improvement, and Fig. 2 is a partial section thereof. Fig. 3 is a face view of a planishing-die for knifeblades having the name, plate, or die inserted. Fig. 4 is a face view of adie for knife-handles having the ornamental portion of the handle on an inserted piece.

This my invention relates to steel dies used in finishingorstampingcutlery; anditconsists in making the die in two or more parts and uniting them together, so that the parts may be separated and other parts substituted therefor. It is especially adapted for use in dies in which one portion is more liable to become more worn from hard usage than another part, so that the more-readily worn portion may be renewed without the expense and trouble of renewing the whole die.

B is made to fit against the shoulders at on the partA and to fit within the place prepared for it in the die A. B has attached to it an extension or plate b, which passes through to the back or bottom of the die A, on which the nut (l is screwed, so as to hold the die B form substantially one die, while at the same time the part B may be removed from A and another part substituted for B. These dies are especially adapted for use in dies having the trade-mark stamp used in finishing cutlery, and such are shown in Fig. 3. They may be used in many other places, and are Well adapted to use in dies for knife-handles where the die is made for a standard handle, the ornament, monogram, or name being produced by the portion of the die which is removably attached to the main portion of the die. (Shown in Fig. 4.

One special advantage in using this form of die for the trade-mark in a planishing-die for knife-blades is that the trade-mark is stamped in the metal when'the whole surface is subject to the die, and the metal around the trade-mark is not compressed more than the other parts.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with the main die provided with a recess in its wearing-surface and an aperture in said recessed part, of a separate auxiliary die having a part adapted to engage said recess, and a screw-threaded extension adapted to pass through said aperture, and a nut for engaging said extension of the die for clamping it in position in said recess, substantially as described.

THOS. SHAW.
